Thread management and control system

Abstract

The invention discloses a thread management and control system, which comprises a class definition module used for respectively defining classes for realizing sub-thread functions and reference control; the task execution module is used for generating a handler object corresponding to the current task, generating a sub-thread corresponding to the current task based on the class for realizing the sub-thread function, and realizing the execution of the current task through the interaction of the handler object and the sub-thread; and the reference control module is used for generating a reference control object corresponding to the current task based on the class for realizing the reference control, and binding the life cycle of the corresponding activity in the execution process of the current task by utilizing the reference control object so as to automatically cut off the reference to the activity after the life cycle of the corresponding activity is ended. According to the method and the device, the corresponding recovery can be realized in time after the activity exits in the task execution process, and the occurrence of memory leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of thread management, and more specifically, to a thread management and control system. Background technique [0002] In the Android system, in addition to immediate response events such as user-visible UI display and interaction, there are relatively long-time-consuming scenarios such as algorithm processing, network requests, file downloads, and data IO. These relatively long-term scenarios usually cannot Do it directly in MainThread, otherwise it will cause the device to freeze severely and cause the application to pop up a notification that it has not responded. [0003] In the Android system, the usual time-consuming operations (algorithm processing, network requests, file downloads, data IO, etc.) will create a new ChildThread to execute, and then display the results to the user after execution; but in the Android system, ChildThread It is not allowed to directly update the page UI information and per...

[0002] In the Android system, in addition to immediate response events such as UI display and interaction visible to users, there are relatively long-time-consuming scenarios such as algorithm processing, network requests, file downloads, and data IO. These relatively long-term scenarios usually cannot Do it directly in MainThread, otherwise it will cause the device to freeze seriously and cause the application to pop up a prompt that does not respond

[0003] In the Android system, the usual time-consuming operations (algorithm processing, network requests, file downloads, data IO, etc.) will create a new ChildThread to execute, and then display the results to the user after execution; but in the Android system, ChildThread It is not allowed to directly update the page UI information and perform user interaction, then use the system class handler provided by the Android system to interact

In this process, the corresponding handler instance of the handler will be referenced by the application MainThread after being created, and the Android basic interface unit activity will be referenced by the handler. The life cycle of the MainThread is accompanied by the survival of the entire application, which will cause an interface activity to exit. , due to the existence of the above reference chain, the activity instance cannot be recycled, and the activity usually references more resources. If the activity cannot be effectively recycled, it will cause a large amount of memory leaks
